Case 2
Alcohol
That night, after your shift, you ask one of your roommates if he's ever experienced difficulties with sleeping or overwhelming sadness and fear. He says that he has. He understands what you're going through.
The two of you sit around the cramped kitchen table, and your friend retrieves a six-pack of beer that he keeps stashed in one of the cabinets. He tells you that beer always helps take the edge off, and the two of you drink together.
